Proficient
Senior / Expert IC
  1. Geothermal plant equipment, electrical systems, and control instrumentation — diagnose complex faults autonomously and implement effective repairs across the full system scope.
  2. Plant and well field operating logs, incident reports, and regulatory documentation — produce complete, accurate, and compliant records independently for all work performed.
  3. Non-routine malfunctions involving mechanical, electrical, and instrumentation systems — analyze root causes using systematic troubleshooting techniques and restore operations with minimal downtime.
  4. Operational data sets from sensors, flow meters, and analytical software — interpret trends, identify performance deviations, and recommend corrective actions to plant management.
  5. Emergency and auxiliary heating or cooling system requirements — determine independently under extreme or rapidly changing weather conditions using critical judgment and system knowledge.
  6. Full pressure, flow, and thermal performance test sequences — plan, execute, and evaluate for both vertical and horizontal loop piping installations to verify system integrity.
  7. Equipment selection decisions for compressors, heat exchangers, and pumps — make informed choices by applying knowledge of mechanical principles, physics, and site-specific operating conditions.
  8. CAD drawings and GIS-based well field maps — interpret and apply to troubleshoot installation geometry issues and plan system expansions in the field.
  9. Systems analysis techniques — apply to evaluate geothermal plant efficiency, identify process improvement opportunities, and present findings using analytical and spreadsheet software.
  10. Complex problem-solving across geothermal installation and maintenance scenarios — lead resolution efforts by coordinating with engineers, inspectors, and field crews to restore or optimize system performance.
Advanced
Lead / Principal / Executive
  1. Geothermal plant operations standards and maintenance protocols — develop, review, and update organization-wide procedures based on operational experience and emerging industry best practices.
  2. Documentation and reporting systems for plant performance and compliance — design and oversee implementation across multiple sites to ensure regulatory accuracy and management visibility.
  3. Technical troubleshooting methodology and diagnostic toolkits — establish and train field teams on systematic approaches for resolving electrical, mechanical, and instrumentation failures.
  4. Data collection and performance monitoring programs — design and direct for entire well field and plant portfolios, using analytical software to drive evidence-based operational decisions.
  5. Emergency preparedness and auxiliary system activation plans — author and coordinate across facilities, ensuring crews are trained and resources are positioned for extreme weather scenarios.
  6. Quality control and testing standards for geothermal loop piping installations — set organizational benchmarks, audit field execution, and lead corrective action processes for non-conforming work.
  7. Equipment procurement strategy for compressors, heat pumps, and ancillary systems — lead vendor evaluation, specification development, and selection decisions at the organizational level.
  8. CAD, GIS, and ERP software platforms — champion adoption and integration across technical and administrative teams to improve installation planning, asset tracking, and reporting efficiency.
  9. Emerging geothermal technologies and system design innovations — evaluate technical viability, lead pilot implementations, and guide organizational investment decisions in new capabilities.
  10. Workforce development programs for geothermal technician teams — design training curricula, mentor developing and proficient technicians, and build organizational depth in installation, maintenance, and operations competencies.
